Do oil paintings really have more "depth" than acrylic paintings like I've heard?

Thus, when compared to acrylic and watercolor paintings, the oil based painting will appear more captivating.
I don’t think that is true. It all depends on the quality of the work and not the medium. A child’s colour crayon scribble of his cat can be on a par with a highly finished oil/acrylic work by a competent artist but it all depends on the viewer.

Art truly only exists when seen and every viewer appreciates different aspects of the work. Deciding what is best or worst is, ultimately, only at a personal level.
